METHOD oFAND MACHINE FORiMAKING WIREGLASS.

Application filed December 2 To all whom it may concern:

Be it known that 1, ROBERT A, B. WALSH,

a citizen of the United States," residing at St. Louis, Missouri, have invented a certain and Machines for lllaking ire-Glass, of which the following is a full, clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of thisspecification, in which Figures 1 and 2 are side elevations of different forms of apparatus which may be used in practicing my invention.

Thisinvention relates to a new and useful method of, and ,a machine formaking wire glass, and particularlywire glass in which a plurality of layers are employed to 'for'nn the ultimate sheet.

a sheet of wire glass having smooth brilliant it hasbeen embedded in the glass.

In the manufacture of wire glass, the tendency of the wire is to contract and draw the glass so as to produce an un- Ithas been proposed, see for illustration the patent to ing them down by a finishing roller; but this cannot' always be successfully accomplished, because, while the finishing roller acts upon the elevations, it will not perfectly transfer the surplus glass to the depressions and makea perfect weld. It has alsobeen proissue patent N0. 12,44t3, dated January 30, 1906, 'to press thewire mesh into the top glass and then spread a finishing layer or sheet of molten glass thereover. Th s method 'producesa better and smoother fin these methods, the wire, on account of-its exposure to atmosphere after being heated,-. loses its bri ht and new ap earanoe and layers occurs principally inthe plane of the wire and as the wire is at places left free Specification of Letters 2mm.

, 1907. Serial No. 494,849.

Briefly stated," my present 'method consists in forming a sheet or layer of glass and drawing a wire mesh into-said layer so that it is completely covered and thereafter forming a second sheet or layer of glass and combining it with the layer that was first formed so that in its. heated condition the wire mesh will not be exposed to atmosphere and will accordingly preserve its bright and new appearance in the finished product.

Patented Nov. 23, 19o9.-

I formed, the second sheet or layer being weld- I ved to that surface of the firsteformed sheet It is obvious that various forms of apparatus couldbe used for practicing 'my method and I have herein shown two forms of apparatus, that which is illustrated in Fig. 1 comprising a, table 1 having a smooth surface roller Q'arranged above the uppersurface [thereofand adapted to spread a mass of molten glass over-the table to-form the bottom layer or sheet, and aair of smooth surface rollers 3' and 4 for orming a separate mass of molten glass into a top layer or sheet, the roller 3 cooperating with the table to combine the two layers or sheets together to --form a single sheet of. glass.- Said apparatus alsofcom'pri'ses a-pair of ten 'sion rolls 5 through which the wire mesh;

passes and a guide roll- 6 so disposed relatively to the roller 2 that the wire mesh will be drawn into the upper surface ofthe hottomvlayer as said layer is-being formed. -In' practicing my method-with an; apparatus of this description, amass of molten glass 7 is dumped onto the table adjacent-the roller 2 and the wire mesh-8 which passes between; the tensionrolls 5 and underneath the guide rolls Sis interposed betweenzthe roller 2 and the mass of-molten glass Thev'table is then moved in the direction of the arrow so that the mass of gla'ss 'lywill be formed v a bottom layer 9,lthe tension rolls and g111(1&

troll causing the wire m;'esh to out its way "into the-mass of glass so that sald meshwill bei'completelycovered-by" glass and, thus while its. heated condition, from"contact with the molten gla$.- When the front end oithe bottom layer or sheet" having the wire 3 aud t. asecond mass of molten glass 10 1. .5 1 b prevented "from oxidizing as would be apt-to'occur if it was exposedto atmosphere is dumped between these rollers which form said mass into a top layer or sheet 11 which is welded to the uneven upper surface of the bottom layer-9 by the smooth surface roller 3. Although I have previously stated that the table is moved longitudinally it will, of course, be understood that this table couldbe stationary and the rollers, tension rolls and guide roll be moved longitudinally thereof without departing from the spirit of my invention.

In Fig. 2 I have shown another form of apparatus which could be used for practicing my method. This apparatus consists of a table 1 having 'a smooth surface roller 2, tension rolls 5 and a guide roll 6 similar to those in the apparatus shown in Fig. 1 for forming the mass of molten glass 7 into a bottom layer or sheet and causing the wire mesh 8 to cut its way into the upper surface of said sheet so that it will be completely embedded. The 'toplayer or sheet 11 is formed by means of smooth surface rollers 3 and 4, and said top layer combined with the bottom layer 9 by means of a smooth surface roller 12 arranged above the table a distance equal to the thickness of the finished product or sheet of wire glass.

It will be observed from the foregoing that a complete sheet of wire glass is first formed, to wit, a sheet or layer of glass with wire buried beneath its up er surface and v finally a finishing layer of glass is formed caused by the wire mesh cutting its-way and combined with the previously formed sheet or layer, the finishing layer of glass filling in the spaces in the first-formed sheet I claim as new and desire to secure by Letters Patent is:

1. An apparatus for making Wire glass,

comprising means for forming a "mass of molten glass into a layer or sheet, lfi'eans for drawing a wire mesh into said sheet so that it is completely covered, and means for forming a second layer or sheet and combining it with the first-formed ,sheet in which the wire mesh is embedded; substantially 'as described.

2. An apparatus for making wire glass, comprising means for forming a sheet or layer" of glass, tension devices for drawing thewire mesh into one surface of said lsheet or layer of glass, and independent means of forming said sheet, and means for forming a second sheet or layer of glass and welding'it to the uneven surface of the firstformed sheet or layer into which the wire mesh is drawn; substahtially as described.

4. An apparatus for making wire glass, comprising means for forming a sheet or layer of glass, tension devices for drawing a wire mesh into the upper surface of said sheet, and means for forming a second sheet or layer of glass and welding it to the upper surface of the sheet in which the wire mesh is embedded; ubstantially as described.

5. An apparatus for forming wire glass, comprisin means for forming a sheet or layer of g ass, tensiondevices for causing a wire mesh to cut its way into the upper surface of said sheet at the time it is being formed, means for forming a second sheet for welding said second sheet to the upper surface of the sheet in which the wire mesh is embedded; substantially as described.

' 6. An apparatus for forming wire glass, comprising means for rolling a mass of molten glass into a layer, means for causing a Wire mesh to cut its way into said layer, means for rolling a second mass of molten glass into a layerwhich passes onto the upper surface of the layer in which the wire-mesh is embedded, and means for combining said layers together to form a single sheet; substantially as described.

7 An apparatus for forming wire glass, comprising a table, a smooth surface roller arranged above said table for forming a mass of molten lass into a bottom layer orsheet, tension r0 ls and a guide roll so disposed relatively to said roller that a wire mesh interposed between said roller and the mass of molten glass will cut its Way into said mass as it is being formed into a sheet, and a second pair of rolls for forming an independent mass' ofglass into a top layer, one of said rollers operating to weld the top layer to the upper surface of the layer in which the wire mesh is embedded; substantially as described.

8. The method of making wire glass, which consists in forming a sheet of glass, drawing a wire mesh into said sheet so that it is completely covered, and progressively forming a second sheet or layer of glass and combining it with the first-formed sheet or layer; substantially as described.
